Our lighting setup (rented accommodation) is a hodge-podge of mixed fittings, including fluorescent tubes and halogen. All of the actual screw (and Edison) fittings have led bulbs in though.

Part of me wishes for the good old days of cheap incandescent bulbs though. The decent LED bulbs are still 10x the price we used to pay for incandescent, so we buy "cheap" ones (4x the price) which don't last any longer than the old tech. Of course you can't get incandescent bulbs anymore..
